Wave soldering compatible with lead free soldering profile. For information on specific and custom switches, consult Customer Service Center. Other versions in terms of force, termination length and corrosion protection available. Packaging Please contact your sales representative. KSF can be delivered in tubes of 65 pieces for automatic insertion This data sheet does not provide enough information for applications which require a or boxes of 500 parts. KSB in boxes of 500 pieces for manual certain level of quality or safety such as automotive, medical systems, safety equipment. insertion. Please contact your sales representative to get contractual specification package. How To Order Our easy build-a-switch concept allows you to mix and match options to create the switch you need. To order, select desired option from each category and place it in the appropriate box. However, please note that all the combinations of these options are not feasible. For any part number different from those listed above, please consult your local representative. SWITCH K S L F T RoHS compliant and compatible. Type Tin plated.
